Abstract
An operating handle for a control device having a control element 11 capable of separate axial and rotational movement is so constructed that each movement is only possible when the handle is in the neutral position for the other movement. The handle consists of a shaft 1 which is rotatable in a sleeve 13 to provide the rotational movement of the control element, the handle being coupled to the control element by means of a pivot pin 10. The sleeve 13 is hinged off its axis using a stay 16 and a link 18, so that the pivotal movement of the shaft causes axial movement of the control element. Therefore, the hinge axis of the sleeve is parallel to the axis of the pivot pin 10. A collar 21 is provided on the shaft for engaging a projection 25 fixed to the body of the control device and a peg 8 secured to the shaft to hold the handle in the neutral position. <IMAGE>
Description
SPECIFICATION
Operating handle for a control device
The invention relates to an operating handle for a control device, in particular for a device having a control element capable of rotational and axial movement.
Operating handles are provided to enable accurately positioning the control elements of control devices, for example of control valves of slide type construction. The accurate positioning relates to the rotational or axial movement of the control element in the body of the device.
Known operating handles of this type have a regulating lever by means of which it is possible to operate a control device either only axially or only rotationally, see French Patent Specification No.
1 380 729.
The problem with which the invention is concerned is to provide an operating handle by means of which it is possibie, starting from a neutral position, to operate a control device rotationally and/or axially and to enable the control element of the control device to be positioned accurately while avoiding jamming actions.
According to the present invention there is provided an operating handle for a control device having a regulating lever by means of which it is possible to move a control element of the control device rotationally and axially, wherein the regulating lever includes a shaft and a guiding member which can be connected in an articulated manner axially to a control element, and the guiding member has a bolt, which at one end is connected in a non-rotatable manner to the shaft of the regulating lever and at the other end can be articulated axially, in a non-rotatable manner, on the control element, a sleeve in which the bolt is rotatably mounted in such a manner that it cannot be axially displaced in it, and a stay laterally mounted on the sleeve, which can be linked to the control device in such a manner that it cannot be rotated and the pivoting of the lever relative to the control element causes axial displacement of the element.
The advantages that can be achieved by the invention lie inter alia in the fact that with the articulated member there is provided an operating handle having a regulating lever that can either be rotated or pivoted out of a neutral position, by means of which handle it is possible selectively to operate a control device rotationally or axially, and in each case to move a control element of the control device without jamming and thus to position it accurately.
Using the proposed structure, namely a bolt, a sleeve and a stay, the guiding member can be of extremely compact and robust construction. The shaft of the regulating lever can, in simple manner, be connected to the bolt in a non-rotatable and axially resilient manner and, by way of the bolt, can be articulated axially, in a non-rotatable manner, on the control element of a control valve.
Furthermore, the bolt can be so mounted in the sleeve that it can be rotated and is held against axial displacement, and the sleeve can be connected in a non-rotatable manner to the housing of the control device by way of the stay. In this manner, firstly, in the case of both rotational and axial operation, a control element can be moved in a trouble-free manner without jamming actions and can thus be positioned accurately and secondly, when it is in an operating position achieved by pivotal operation, the regulating lever cannot be rotated and when in an operating position achieved by rotational operation, the regulating lever cannot be pivoted and thus, in this respect, cannot be moved to a false position whatever its operating position.
The shaft of the regulating lever can, in simple manner, be so arranged in a longitudinal bore in the bolt that it can be moved against the force of a spring and is guided, in a non-rotatable manner, by way of a longitudinal slot in the bolt and a peg attached to the shaft. This has the advantage that the regulating lever can be guided by means of the peg also in a rotational direction in a transverse groove in the sleeve, it being possible to provide the transverse slot with locking recesses in which the peg is held in a positive manner by the force of a spring and in which in the case of rotational operation, the regulating lever can be maintained in certain operating positions.
A retaining collar can be arranged on the regulating lever to have the effect that when the regulating lever is in its neutral position it can be held against unintentional rotational or pivotal operation.
The invention will be described in the foliowing with reference to an embodiment which is shown in the drawings, of which: FIGURE 1 shows a longitudinal section through an operating handle on a control device in the form of a control valve shown in outline; and
FIGURE 2 shows a side view of the operating handle of Figure 1.
The operating handle shown in Figure 1 has a regulating lever with a shaft 1 which at one end has a rigidly attached knob 2 and at the other end is fitted to a guiding member 3. The guiding member 3 has the bolt 4 which is provided at one end with an axial blind bore 5. In the blind bore 5 the end of the shaft is movably guided and constrained by the force of a spring 6 which is located at the base in the blind bore 5. Beside the blind bore 5 the bolt 4 also has a longitudinal slot 7 in which a peg 8, projecting radialiy from the shaft 1, engages, so that the shaft 1 is moveably guided in a non-rotatable manner in the blind bore 5.
At the end of the bolt 4 remote from the shaft 1 there is formed an eyelet 9 by means of which the bolt 4 is articulated axially on a control element 11 of a control valve 12 with a pin 10.
The guiding member 3 has, in addition, a sleeve 13 in which the bolt 4 is so mounted that it can be rotated but is held against axial displacement by clips 14 and 15 on the pin. The sleeve 13 is connected in a non-rotatable manner to the control valve 12 by means of a stay 1 6.
The stay 1 6 is rigidly attached to the sleeve 13 and projects to one side of the sleeve. At its free end the stay 1 6 is hinged to one end of a link 1 8.
The other end of the link 1 8 is hinged on the housing of the control valve 12, so that the sleeve 13 is connected to the control valve in a nonrotatable manner but, with the shaft 1, can be pivoted in a direction towards or away from the point of articulation of the stay 16 and link 18 on the control valve, with the result that the distance of the point of articulation (the pin 10) of the bolt 4 to the control element from the housing of the control valve 12 can be altered.
The sleeve 13 has a transverse slot 1 9 in which the peg 8 engages and limits the axial displacement of the shaft 1 in the bolt 4 and the rotational movement of the bolt 4 in the sleeve 13.
At one side of the transverse slot 1 9 there are provided locking recesses 20 in which the peg 8 is pressed by the force of a spring 6 so that the regulating lever can be held in positions achieved by rotational operation.
A retaining collar 21 is movably arranged on the shaft 1, which collar 21 has, on the side of the guiding member 3, a hollow space 22 adapted to the circumferential shape of the member 3 and, beside the hollow space 22, a first longitudinal slot 23 and a second longitudinal slot 24. The retaining collar can be pushed so that its hollow space 22 accommodates the member 3, the first longitudinal slot 23 being guided onto the peg 8 and the second longitudinal slot 24 being guided onto a holding projection 25.
The holding projection 25 is attached to the housing of the control valve 12 axially parallel to the control element 11 and displaced by 900 with respect to the point of articulation of the stay 16 and link 18 on the control valve. The longitudinal slots 23 and 24 of the retaining sleeve 21 are so arranged that the retaining collar 21 can be pushed onto the guiding member 3 only when the member 3 is aligned axially with the control element 11 and the pin 10 lies at right angles to the pivot plane of the regulating lever. This position of the regulating lever is its neutral position from which it can be operated either rotationally or pivotally and in which, when the retaining collar 21 is pushed onto the guiding
member 3, it is safeguarded against unintentional
rotational or pivotal operation.
The two longitudinal slots 23 and 24 may, as in the embodiment shown, conveniently be arranged diametrically opposite and interchangeabiy if, in
order to ensure the functioning of the retaining collar 21 described above, the longitudinal slot 7
in the bolt 4 is arranged axially parallel with the
eyelet 9.
On the shaft 1 there is formed an annular
enlarged portion 26 which, as shown, may be a spring ring in a groove on which the retaining
collar 21 can be locked when it has been pushed
back out of the engagement with the guiding
member 3 to permit operation of the regulating lever.
The mode of action of the operating handle described so far is as follows:
The drawing shows the operating handle in its neutral position in which the guiding member 3 is aligned axially with the control element 11 and the pin 10 is at right angles to the pivot plane of the regulating lever.
Starting from the neutral position of the operating handle it is possible selectively to operate the control element 11 of the control valve 12 rotationally or axially.
The axial operation of the control element 11 is provided by pivotal operation at the regulating lever in a direction towards or away from the stay 16. When the pin 10 is at right angles to the pivot plane, the shaft, together with the guiding member 3, can be pivoted about a point to one side of the sleeve 1 3, the distance of which point from the control valve 12 is set by the stay 16, with the result that the operating force applied to the regulating lever is amplified by the leverage and acts axially on the control element 11. Thus the control element 11 can be moved axially without jamming and can be positioned accurately. The control element 11 can be held in any desired axially displaced position by customary locking elements inside the valve (not shown).
The rotational operation of the control element 11 is effected by corresponding rotational operation of the regulating lever 1. The shaft 1 can be rotated when the guiding member 3 is aligned axially with the control element 11. Once the pin 10 is no longer at right angles to the pivot plane of the regulating lever as defined by the articulation of the stay 16 and link 1 8, the sleeve 13 is held by the stay 1 6 in such a manner that its distance from the control valve 1 2 cannot be changed, and the bolt 4 is rotatably guided in the sleeve 13 to be axially aligned with the control element 11. The shaft I is resiliently constrained in the bolt 4 by the spring 6 to cause the peg 8, movable in the longitudinal slot 7 in the bolt 4, to enter the recesses 20 in the transverse slot 19 of the sleeve 13.
In its neutral position the operating device can be safeguarded against unintentional operation by the retaining collar 21.
For this purpose, the retaining collar 21 which, during operation, is held up by the annular enlarged portion 26 on the regulating lever 1, is
released from its locked position and is pushed down onto the member 3 with its first longitudinal slot 23 fitted on the peg 8 and its second
longitudinal slot 24 fitted on the projection 25. On so doing, the retaining collar 25, which is fixed to the housing of the control valve 11, and the peg 8
ensure that the regulating lever 1 cannot be
operated either rotationally or pivotally.
A handle according to the invention can be
used in conjunction with any type of control
device having a control element capable of
separate axial and rotational movements.
Modifications can be made to the embodiment described; for example, the peg 8 need not be opposite the projection 25 in the neutral position, but the slots 25,24 in the collar 21 must be altered correspondingly, and the construction of the guiding member 3 may be changed in many ways using mechanical equivaients of the parts described.
